I will say, in the past I have usually flown SWA, including our recent trip to the Caribbean, via Orlando. Most of the flights, however, have been Sacramento to LA, Sacramento to Phoenix. On my recent trip to Nashville, I flew Frontier; there was a significant difference in seat size between these two airlines. On a short flight, I'll still go SWA, but on anything longer than two hours, I'm likely to choose another carrier, just for the little bit 'o extra butt space in the seat... not suggesting that I NEED the extra butt space, it's just nice to have when, like me, you have that stamp on your forehead that says "really large people, please sit next to me." I'm not knocking large people, either; I'm 6'2 and pushing 250 (I'm large boned and don't look a pound over 225).
